摘要：

Sparked by the increasing energy crisis, much research has been focused on seeking board spectrum-driven photocatalysts for water splitting. Herein, the Ni3(C₃N₃S₃)₂ coordination polymer was firstlysynthesized by a simple wet-chemical method, as a novel board spectrum-driven photocatalyst forwater splitting. The as-prepared Ni₃(C₃N₃S₃)₂ exhibited excellent photocatcalytic H₂-producing activityfrom the half-reaction of water splitting without the help of any sacrificial agents or cocatalysts, andthe amounts of H2production are 65.3, 53.9 and 16.3 mol corresponding to UV ( < 400 nm), visible(400 ≤  ≤ 760 nm) and near-infrared ( > 760 nm) irradiation after 24 h, respectively. Another valuablefinding is that after adding triethanolamine as a sacrificial donor, the average H₂ evolution efficiencies onNi3(C3N3S3)2were efficaciously increased by around 2-fold with the H₂ production value of 112.6, 93.3and 30.1 mol for 24 h under the UV light, visible light and near-infrared light exposure, respectively.More importantly, the stability of Ni3(C3N3S3)2was effectively improved by means of triethanolamine.The results facilitate the increasing attention of narrow band gap non-noble metal coordination polymerstreated as board spectrum-driven photocatalysts for expanding the utilization of solar light.
